To all whom, it may concern:

Be it known that I, CARLETON ELLIS, a citizen of the United States, and now residing at Montclair, county of Essex, and State of New Jersey, have made a certain new and useful Invention Relating to Finish-Removers, of which the following is a specification.

This invention relates especially to substantially non-aqueous finish removers preferably containing oxalic acid or similar wood bleaching agent and which may contain terpineol and otherfinish solvents of a ing up some of the water usually present in alcoholic and similar finish solvents so as to proportionately minimize undesirable hydrolysis in connection with chlorinated solvents. Carbon-tetrachlorid is a desirable chlorinated solvent having valuable inflammability suppressing properties in this connection and pentachlorethane or tetrachlorethylene or similar actin chlorinated solvents may also be used. erpineol and pine oil and the like also seem to have a desirable preserving action in such non-inflammable removers, as well as'bei desirable penetrating finish solvents. Ot er suitable penetrating; finish solvent material may be employed, that is, finish softening material of a generally benzolic character or action in re-' movers, such as benzol and its homologues, toluol, xylol, and their commercial forms such as commercial toluol and the high boiling point coal tar, solvent naphtha and also the somewhat analogous petroleum hydro carbons, such as benzin, light kerosene, and so forth, as well as turpentine, wood turpentine, tar oil and other chlorinated solvents such as chlorinated benzol, dichlorhydrin and e ichlorhydrin, although of course it is un erstood, that the morevolatile solvents iving oif inflammable vapors are undesirab e for use in large proportions for non-inflammable removers.

Suitable looseni finish solvent material ma also be used, t at is, solvents of a gen-.. era ly alcoholic character or action in removers, such as methyl, ethyl, pro yl, butyl,. ainyl, allyl and other-strict alcoho s, preferably in their commercial forms, including denatured alcohol or their esters derived from combination with acetic, carbonic, butyric, propionic, formic, carbolic, cresylic, lactic, citric and other acids. 'Many ketonic bodies having a 'enerally alcoholic character or action may a obe used, such as methyl ethyl ketone, ethyl butyl' ketone, oil of acetone, acetone and its condensation derivatives, mesityl oxid, phorone, xylitone and isoxylitone as well as methyl acetone and the secondary and tertiary alcohols and their derivatives.

An illustrative substantially non-inflammable remover ma comprise 40 gallons of ethylor denatured alcohol, 20 gallons of terpineol, 40 gallons of'carbon-tetrachlorid, 20 pounds of parafiin and 3 to 5 per cent. or so, say 30 pounds, of dry finely divided ox alic acid.

Another non-inflammable remover ma comprise 50 gallons of denatured alcoho,

10'gallons of pine oil, 40 gallons of carbontetrachlorid, 3.0 pounds of parafiin or ceresin wax and 35 pounds of oxalic acid.

Another illustrative remover may comrise 100 gallons of benzyl alcohol, 60 gallime of ethyl alcohol, 40 allons of carbontetrachlorid, 30 pounds 0 ceresin wax and 50 pounds of oxalic acid either with or without the use of turpentme, pine oil, terpineol or other preservative.

Another illustrative remover which does not have non-inflammable properties may comprise wood alcohol, 50 ga lons, benzol, 40

ga lone, paraflin, 20 pounds, and oxalic acid wood bleaching material such as oxalic acid or acid ammoniumpxalate, 35 pounds.

Another illustrative remover suitable for general. use may comprise 60 gallons of hen- $01, 40 to 50 gallons of wood alcohol or, methyl acetone, 20 pounds of waxy stifiening material such as parafiin or ceresin, and 3 to 4 per cent; by wei ht of oxalic acid. It is of course understoo that the oxalic acid,

thorou hly dried at 120 C. or so and finely groun may be readily dissolved in'the al- 110 cohol or similarly acting loosening finish solvent and the Waxy material dissolved in the solvent therefor and the two solutions incorporated at a slight heat, if desired.

Another illustrative remover may comprise ethyl citrate 10 gallons, terpineol 5 gallons, gasol'ene 5 gallons, denatured alcohol 10 gallons, wood flour 15 pounds and chlornaphthalene 45 pounds.

Another remover may. comprise allyl alcohol 10 gallons, camphor 5 pounds, paraflin 3 pounds and wood flour 8 pounds.

Another remover may comprise denatured alcohol 15 gallons, acetone 10 gallons, benzol 10 gallons, benzin 5 gallons and beta naphthol 30 pounds.

Another remover adapted for removing shellac and similar finish may comprise wood alcohol 12 gallons, terpineol 10 gallons, naphthalene 5 pounds and ceresin 2 pounds, although the wood alcohol is not necessary when the remover is used on other finishes.

Another remover may comprise terpineol 10 gallons combined'with chlornaphthalene 7 pounds.

Still another illustrative remover may comprise terpineol 8 gallons, acetone 6 gallons and benzophenone 9 pounds.

' Although not necessary in all cases it is usually desirable to employ in the remover in addition to the crystalline organic evaporation retardin material other suitable stiffening material, such as wood flour, starch, Whiting, infusorial earth and soa y or waxy bodies, such as ceresin, para bayberry tallow, beeswax, ozocerite, tar oil and the like. All of the ingredients are preferably thoroughly incorporated by agitation at the desired moderate heat, the stiffening material being preferably first incorporated with the more energetic solvents, although this is not always necessary.

Having described this invention in connection with a number of illustrative ingredients,'formulas, proportions and processes, to the details of which disclosure the invention is not of cource to be limited, what is claimed as new is:

1. The substantially non-aqueous non-inflammable finish remover, comprising ap proximately 40' gallons of ethyl alcohol, 20 gallons of terpineol, 40 gallons of carbon-. tetrachlorid, with which 20 pounds of paraffin and 30 pounds of previously dried oxalic acid have been incorporated.

2. The substantially non-aqueous non-inflammable finish remnver, comprising approximately 40 gallons of ethyl alcohol, 20 gallons of terpmeol, 40 gallons of chlorinated solvent, waxy stifi'ening material and 3 to 5 per cent. of oxalic acid. 1
